I'm REALLY confused right now.
I've think I followed the "Steps to manage updates for Windows 10" guide to the letter (https://technet.microsoft.com/itpro/windows/update/waas-deployment-rings-windows-10-updates).
I changed in two GPO's to Defer Updates. One for all clients in production, that was set to Current Branch for Business and to wait 90 days after the release of a new CBB version. The other one is for the test clients, that was set to Current Branch, and wait 30 days.
Then I followed the SCCM part of the guide and created two Device Collections based on the Branch Readiness settings on the machines and setup two different Servicing Plans based on those collections (https://technet.microsoft.com/itpro/windows/update/waas-manage-updates-configuration-manager).
All is well, or so I thought...
I just found this Microsoft blog post, I read Scenario 2 and went "WTF?!" (https://blogs.technet.microsoft.com/windowsserver/2017/01/09/why-wsus-and-sccm-managed-clients-are-reaching-out-to-microsoft-online)
This is confusing...
Can you guys explain this to me?
Thanks
